American exceptionalism is what keeps Americans from truly exercising their power. American power is insane and that power is what leads to transgressions. If you remove American exceptionalism, the thing that compels America to try and behave morally/with principle, the world would be in serious trouble. American cynicism is probably what you should be worried about. When American leaders no longer have to come up with a moral justification and instead can claim national interest alone America will become a lot more aggressive.
Exactly.
America alone has altruistically created a peaceful and safe world for billions of people. We will continue shouldering the burden until the entire world is peaceful, safe, and prosperous.
In 200 years, the world with look back with admiration on our foreign policy, and embarrassment on those who currently want America to apologize for standing up for basic human rights.
